The natives soon lost all fear of the airship, and some of the chief men even consented to come aboard.  Tom gave them a few trifles for presents, and won their friendship to such an extent that a great feast was hastily gotten up in honor of the travelers.  Big fires were lighted, and fowls by the score were roasted.

“Say, I’m glad we struck this place!” exclaimed Ned, as he sat on the ground with the others, eating roast fowl.  “This is all to the chicken salad!”

“Things are coming our way at last,” remarked Tom.  “We’ll start the first thing in the morning.  I wish I had my camera now.  I’d take a picture of this scene.  Dad would enjoy it, and so would Mrs. Baggert.  Oh, I almost wish I was home again.  But if I get my camera I’ve got a lot more work ahead of me.”

“What kind?” asked Ned.

“I don’t know.  I’m to stop in Paris for the next instructions from Mr. Period.  He is keeping in touch with the big happenings of the world, and he may send us to Japan, to get some earthquake pictures.”

The night was quiet after the feast, and in the morning Tom and his friends sailed off in their airship, leaving behind the wondering and pleased natives, for our hero handed out more presents, of small value to him, but yet such things as the blacks prized highly.

Once more they were flying over the trail, and they put on more speed now, for they were fairly sure that the men they sought were ahead of them about a day’s travel.  This meant perhaps twenty miles, and Tom figured that he could cover fifteen in a hurry, and then go over the remaining five slowly, so as not to miss his quarry.

“Say, don’t you smell something?” asked Ned a little later, when the airship had been slowed down.  “Something like smoke?”

“Humph!  I believe I do get an odor of something burning,” admitted Tom, sniffing the atmosphere.

“Bless my pocket book!” exclaimed Mr. Damon, “look down there, boys!” He pointed below, and, to the surprise of the lads, and no less of himself, he saw many animals hurrying back along the jungle trail.

There were scores of deer, leaping along, here and there a tawny lion, and one or two tigers.  Off to one side a rhinoceros crashed his way through the tangle, and occasionally an elephant was seen.

“That’s queer,” cried Ned.  “And they’re not paying any attention to each other, either.”

“Something is happening,” was Mr. Nestor’s opinion.  “Those animals are running away from something.”

“Maybe it’s an elephant drive,” spoke Tom.  “I think—­”

But he did not finish.  The smell of smoke suddenly became stronger, and, a moment later, as the airship rose higher, in response to a change in the angle of the deflecting rudder, which Ned shifted, all on board saw a great volume of black smoke rolling toward the sky.

“A jungle fire!” cried Tom.  “The jungle is burning!  That’s why the animals are running back this way.”
